Hello i'm 21 years old from Greece and I'm currently studying economics in university of Athens.I wasn't sure what i wanted to become so i decided to join economics because it seamed interesting.A personal experience motivated me to become a dermatologist especially in the research area.Should i finish my studies in the next 2 years and try to become a doctor in America or is it already too late ?I have relatives living in Pennsylvania.I would also like to ask how many years does it take for someone to become a dermatologist and how much does it cost.
